Cabin totals pass FlightQ's internal validation; a public source link is not currently available, and partial-row positions may be approximate. The map cannot render unless its seat-by-seat count reproduces the published totals exactly (20J + 155Y = 175 on this aircraft). Per-seat notes are rewritten into plain-language warnings for row selection.
